ADDISON A. CARDWELL, OF RYE, NEW YORK.

HUMIDIFYING MEANS FOR USE IN CONJUNCTION WITH HEATING APPARATUS.

Application filed March 16, 1914.

To aZZ whom it may concern:

Be it -:nown that I, ADDISON A. CARD- wnLL, a citizen of the United States, and a resident of Rye, county of lVestchester, and State of New York, have invented certain new and useful Improvements in Humidifying Means for Use in Conjunction with Heating Apparatus, of which the following is a specification.

The object of my present invention is to afford simple but effective automatic means whereby the heat of an ordinary steam, hot Water, or hot air furnace may be utilized in furnishing humidifying vapor to the airin one or more apartments or inclosures, to counteract the deleterious effects of an abnormally dry atmosphere, substantially as set forth in my concurrent application. Serial No. SQOAO-t, filed Feb. 24th, 1914, so that lack of desirable atmospheric moisture caused by artificial heating may be compensated for, in whole and in part, and so that the humidifying vapor may be impregnated if desired with a. volatile perfume, deodorizer, disinfectant or medicament, before introduction into the air to be humidified.

In the accompanying drawings, Figure 1, is a diagrammatic view representing symbolically the practical application of my invention; Fig. 2 is a front view of the feed trap, partly broken away; Fig. 3, is a top view of the trap; Fig. 4, a vertical sectional elevation taken upon plane of line 4-4 Fig. 3; Fig. 5, a sectional detail of the impregnator.

A, represents symbolically a furnace of any character such as used for heating dwellings, &c., and it may be of steam, hot air, or hot water, or any other type, according to circumstances,my vaporizing chamber '0, being positioned in the combustion chamber a, as a convenient situation for the acquisition of the heat essential to the oper' ation of my system of humidification; or

the necessary heat to effect evaporation may be imparted to the vaporizing chamber 1*,

. by any other means, as may be found most expedient in practice.

The vapor generated in the chamber r. is conducted by one or more pipes a, to the apartment or apartments, the air in which is to be humidified; or in the case of a hot air furnace the vapor may be conducted from the vaporizing chamber n. directly into the hot air chamber of the heater, to mingle and flow with the hot air supply.

Specification of Letters Patent.

Serial No. 825,036.

lVhere a stand pipe a is used as a means of distribution it may be inclosed in the wall structure and provided with a discharge hood a", opening into the apartment.

When it is desired to impregnate the moist vapor with a volatile perfume, deodorant, disinfectant or medicament, I provide the stand pipe a with a receptacle a, for such volatile material, preferably in the form of a' cup connected to the stand pipe by means of a short duct d, through which the volatile emanations escape from the cup a, into the stand pipe, to be absorbed by the vapor passing therethrough.

lVater is supplied to the evaporating chamber 1*, through the medium of my feed trap 13. interposed between a branch (1, of the water service pipe and said evaporator w, as indicated in Fig. 1,c, being a valve in the service pipe C, by means of which the water may be shut ofi from said feed trap when desired. as at night when the fire in the furnace is banked, when thehcater is out of service, or when the atmosphere is compartment 6, some distance above the bottom thereof, so that the lower portion of the compartment 1), constitutes a. settling pocket b", for the reception of the coarser sediment, which may be blown or washed out from time to time through the hole 6, closed normally by the screw plug b. As the passage of water through the feed trap B, is comparatively slow, escaping therefrom as it does drop by drop as hereinafter set forth, there is ample time for the gravitation of the coarser particles of foreign matter in the feed water into the pocket 1)", before said feed water enters the filtering chamber 5 through the duct 5''. in the partition wall 2'). of the trap B, as will be understood by referenceparticularly to Fig. 2, of the drawings.

The filtering compartment 6 and the drip chamber 6 are in vertical alinement,

orsubstantially so, and are separated by a transverse partition 6, of ample thiclmess, formed with a valve seat 6, interposed in the drip duct 6", which extends through the partition I), from the bottom of the filter ing chamber 6 to the top of the drip'chamber b ,the available area of said valve seatfront of the casing and being provided with 7 means whereby the screw valve may be readily manipulated to regulate the escape of water from the filtering chamber .71

A dial 6, may be arranged on the face of I the casing concentric to the needle valve E,

and the latter may be provided with an index 6 to facilitate the setting of the valve. An arch or dome f,.of wire gauze or similar foraminous material, may be placed in the bottom of the filter compartment 6 to space the filtering material F, away from the drip ductb, as shown in Fig. 2.

In order to centralize the drip from the duct f", and insure its descent visibly when observed through a sight glass 8, mounted for the purpose in the front of the trap B, I provide a funnel g, mounted on a bracket g, the. funnel being positioned in alinement with the lower end of said duct 6", as shown in.Fig.2. I

- The lower portion of the drip chamber 6 merges into the lower portion of the discharge cha'mber'b as-shown in section in Fig. '3, and the discharge conduit d, connected with the'latter prescribes the water level therein, and in the drip chamber 1),

also,-saidwater level being discernible through the sight glasses .9, 8, provided for urposes of observation. Thus the drip om the filter chamber b may not only be observed, or the absence thereof noted, but it is also possible to ascertain by a comparative glance whether the trap is properly sealed and operative.

The U-shaped connection between the drip chamber 6 and the discharge chamber 6, affords an additional trap or well for the elimination from the actual feed escaping through the exitpipe d, of any matter other than li uid that might by any possibility escape t e settling pocket 6', and filtering material F. By this means the evaporating chamber/ 4), is effectually protected against all danger of incrustation by sedimentary deposits that might otherwise result therein during the evaporation of the feed water.

A blow ofi' or wash out aperture is provided at the bottom of the U-shapedconnec tion between the drip chamber 6 and the discharge chamber 2 said aperture being closed normally by a screw plug 6 Likewise the upper ends of the receiving chamber b, of the filter chamber 6 and of the discharge chamber 6 are closed respectively and normally by screw caps or plugs Z7 b b, which affords means of access to the said compartments when necessary.

A water seal h, is provided at the junction of the stand pipe a, with the vapor discharge pipe a, from the evaporating chamber a. This trap which is simply. a U-shaped pipe connection open to the atmosphere at its outer end, prevents the escape of vapor at that point while affording an escape for an overflow of water should the heat in the evaporating chamber '0, be insufiicient to vaporize the feed from the trap B. Presumably the valve 0, in the supply pipe 0, is closed when the fire in the heater A, is banked for the night, or the heater is not in use, and the provision of the overflow trap h, is simply a matter of precaution to prevent a head of water in the distribution or stand pipe at.

The needle valve E, admits of the regulation of the feed drip with accuracy,'according to requirements. The elimination of all foreign matter from the water feed prevents clogging and incrustation, and insures a supply of humidifying vapor uncontami nated with objectionable odor of any kind.

\Vhat I claim as my invention and desire to secure byLetters Patent is,
